Information
MMCX connector is one series of RF connectors. This MMCX connector is jack/ female, and straight bulkhead type. This MMCX jack bulkhead type will be terminated with RF Coax Cable to be MMCX cable assembly for signal transmitting. The applicable RF coax cable is RG174/ RG316/ RG178/ LMR100/RD316/RG188 RF coaxial cable. Its plating is Gold over brass and the impedance is 50 ohm.
MMCX connector is kind of small in RF connector. MMCX Connectors have snap-on mechanical mating design. Besides, MMCX jack crimp series still have Right angle jack , straight crimp jack, PCB mount jack, edge mount jack and SMT jack. MMCX Connector commonly is used for 0~3GHz. If you need higher working frequency, special mechanical design, customized RF connector, or RF cables, please contact us.
MMCX connector jack straight bulkhead crimp type can be terminated with RG174/ RG316/ RG178/ LMR100/RD316/RG188/RG196 RF coaxial Cable to be RF Cable assembly. It can transmit RF Signal well in various telecommunications. MMCX RF connector is most commonly used in GPS internal Antenna, GSM external Antenna or GPS/GSM application these kinds of RF industry.
